Impossible to suffocate if CO2 does not build up?

Even if one were theoretically awake during SN or exit bag, it sounds like suffocation feeling is only a reaction to CO2 buildup, correct? Thanks

Yeah, that's correct.

Your body can detect CO2 buildup, and that triggers a response. Without that you won't feel anything until you pass out.

Why are there reports of shortness of breath on SN then?
